Yeah I'm still trying to get this damn stem out after 'coming back' to it last night after a 6 month lay off! Shortly after i wrote this post i tried the industrial strength ammonia method but it had no effect. So yesterday I cut two slits in the stem down to the bare bone of the fork steerer with a hacksaw blade, I then got some locking pliers and tried to bend the stem in on itself, but, all the pliers seem to do is crush and mess up the 1/2 inch of stem thats sticking out of the steerer (where i cut it off). I was thinking of crushing this 1/2 inch sticking out part together in a vice to get more leverage and pressure - Then again I don't know if this method would make the lowest part of the inner stem expand and bulge and perhaps cause more trouble. What do you think?

*I will try and get some snaps...
